Within the experiment, the osmotic dehydration of apple in the sugarbeet molasses at a temperature of 55 º C and atmospheric pressure was performed. Drymatter content in apple was increased from 13.58% to 52.3%. During the experimentalwork, dry matter content, contents of sugar and some minerals (K, Na, Ca and Mg) inmolasses before the process and after 1, 3 and 5 hours of immersion, were determinated.The results of this paper indicate that, during the osmotic dehydration, sugar beetmolasses do not decrease in quality, moreover its enriched with some elements, and canbe used as a component of food for animals. In this way, sugar beet molasses, as highquality raw material, could be used in two different technological process.Key words: sugar beet molasses, osmotic dehydration, food for animals, appleINTRODUCTIONSugar beet molasses is a concentrated liquid extract that is a by-product of sugarrefining. Molasses has a high content of solids (around 80%) and contains, in average,51% saccharose, 1% rafinose, 0.25% glucose and fructose, 5% proteins, 6% betaine,1.5% nucleosides, purine and pyramidine bases, organic acids and bases and pectines[9].Molasses contains, in very small amounts (about 0.02%), amides, ammonia salts andnitrates. Of all amino acids, the most common is glutamic acid - about half of the totalamount of amino acids. In the molasses there is the oxalic acid (0.01%), oxyglutic acid,lactic (0.5%), saccharic acid, humic acid, arabic acid and gliceric acid [2].Apart from these ingredients, sugar beet molasses is a significant source of numerousmicronutrients (vitamins and minerals), especially K, Ca, Na and Mg. Speciallyimportant is the fact that all mineral components of molasses are in the dissolved stateand that the potassium is in much greater quantity than all other cations with share of75% [9].In addition to these minerals, in the molasses are also small quantities of the followingelements expressed in mg / kg: Co = 0.59, B = 3.0, Fe = 115.0, Cu = 4.9, Mn = 18.0, Mo= 0.20 and Zn = 34.0.230
